ADJUSTABLE CYCLOMETER.

SPECIFICATION forming part of Letters Patent No. 510,328, dated December 5, 1893.

Application filed May 12, 1893. Serial No. 474,021- (No model.)

To (0% whom, it may concern:

Be it known that I, CHARLES COULERN- MEURI, a citizen of Switzerland, and a resident of ChauX-deFonds, Switzerland, have invented a new and useful Improvement in Apparatus for Registering the Distance Traveled Over by Vehicles, of which the following is a specification.

My invention relates to a new or improved apparatus or meter for measuring and registering on a dial the number of itinerary units such as miles, kilometers, &c., traveled over either by a velocipede or wheel vehicles; and 1n order that my said invention may be fully understood,l have illustrated an apparatus constructed according to the same in the accompanying drawings, in which- Figure l is a plan view of my improved ineter, the dial and pallet-plate 6 being removed. Fig. 2 is an axial section made upon line AA Fig. l of the meter. Fig. 3 is a plan view of the meter, the dial 0 being broken away for showing the pallet plate c. Fig. 4 is a side elevation of the meter showing the end of the connecting cable. Figs. 5 and 6 are respectively a plan view and a side elevation of the coil threaded plate. Figs. 7 and 8 are respectively a side elevation and a plan view of the endless screw threaded disk.

A disk a is secured by a pin 0 to a plate Z) clamped on a spindle t. This spindle which carries the great hand Z is fitted loosely in the bottom of the metallic box g which is the casing of the meter, and also in the palletplate e. The disk a is thus connected with a hand Z and is rotated by a roller 7'. This roller is titted on a horizontal grooved shaft It and may, by means of the adjusting screw 11 acting on the double square 19, be brought nearer to or farther from the center of the disk 0., in order to change the ratio of the relative speed of the spindles t and 75.

A spring d Fig. 52 keeps constantly in contact the disk a and the roller 9* and secures their adherence. A small roller g, located opposite the roller '2 prevents an excessive bending and keeps the disk a perpendicular to its spindle Fig. 2.

In Fig. 3, the hand Z indicates for each turn of the dial aten itinerary units (kilometers or miles) and the hand w, one hundred units. The difference of speeds between the two hands is obtained by means of a set of gears m like the minute-wheels in a watch. A small dial recording thousand units or more, it necessary, may also be provided, in which case it should be arranged as shown at "i Fig. 3. A small cam U, secured on the wheel carrying the hand 00, rotates at each turn of the latter, of one tooth a ten teetl1-star-wl1eel carrying the hand of the small dial I. The return of the hands to Zero, is effected by pressing on the knob 92 Fig. The adherence be tween the roller 1 and disk a is thus interrupted and the hands may be easily rotated. hen the pressure is released, the spring (1 is pulled back to its first position.

It will readily be understood that I may also apply to my improved meter the system known as handless watch system, in which the hands are replaced by disks carrying figures which appear in wickets provided in the dial.

The shaft h is rotated by means of an endless screw V acting on a worm wheel 3, the said endless screw being connected by a flexible cable A Figs. 4, 5, and 7 by means of a nipper or coupling B or any other suitable connecting device. This cable has for its object to connect the screw V of the meter with a toothed wheel 0 Figs. 5 to S, gearing with a coil-threaded plate D mounted on the axle of the vehicle wheel.

In some cases the wheel 0 gears with an endless screw threaded disk E Figs. 7 and 8, mounted on the axle of a vehicle or velocipede.

The double square p Figs. 1 and 2, is graduated on a part which may project out of the box,this graduation corresponding to the several diameters of wheels. It is then sufficient, when setting the meter to its place, to put by means of the adjusting screw 3 the double square 19 on the division corresponding to the diameter of the driving-wheel.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent of the United States, is

l. The combination with a casing or box q, a dial, and pointers, of a center spindle t, a disk CL connected with the spindle, a shafth having a worm-wheel s at its outer end, a friction-roller r keyed to the said shaft, adjustable along the length thereof and rotating therewith, a rectilinearly-moving graduated square 17 connected with the friction-roller for rotating the said friction-roller-carrying shaft, and a spring d interposed between the 15 said pallet-plate of the casing or box and the said disk for pressing the latter against the friction-roller, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscrib- 2o ing witnesses.

CHARLES COULERN-MEURI.
